10 - Karen Read First Trial - State Witness Testimony - Matthew Kelly

This is the first trial of Karen Read, the Massachusetts woman accused of striking her Boston police officer boyfriend with her sport utility vehicle and leaving him to die in a snowbank. Read, 43, of Mansfield, has pleaded not guilty to second-degree murder and other charges. The prosecution says she hit her boyfriend, John O'Keefe, with her vehicle outside of a home in Canton during a snowstorm on Jan. 29, 2022, following a night of drinking. Her defense plans to argue that someone else is responsible for killing O'Keefe.
